您可以使用命令的--help来了解参数。

$ ./bin/neo4j --help
Usage: neo4j [-hV] [--expand-commands] [--verbose] [COMMAND]
A partial alias for 'neo4j-admin server'. Commands for working with DBMS process from 'neo4j-admin server' category can
be invoked using this command.
      --expand-commands   Allow command expansion in config value evaluation.
  -h, --help              Show this help message and exit.
  -V, --version           Print version information and exit.
      --verbose           Prints additional information.
Commands:
  version  Print version information and exit.
  help     Displays help information about the specified command
  console  Start server in console.
  restart  Restart the server daemon.
  start    Start server as a daemon.
  status   Get the status of the server.
  stop     Stop the server daemon.

Environment variables:
  NEO4J_CONF    Path to directory which contains neo4j.conf.
  NEO4J_DEBUG   Set to anything to enable debug output.
  NEO4J_HOME    Neo4j home directory.
  HEAP_SIZE     Set JVM maximum heap size during command execution. Takes a number and a unit, for example 512m.
  JAVA_OPTS     Used to pass custom setting to Java Virtual Machine executing the command. Refer to JVM documentation
about the exact format. This variable is incompatible with HEAP_SIZE and takes precedence over HEAP_SIZE.

因此，要为neo4j.conf文件提供一个特定的位置，您需要将其作为环境变量传递。

export NEO4J_CONF=/path/to/neo4j.conf && ./bin/neo4j start

当你启动数据库时，你可以看到右边3个点。2在里面点击打开文件夹〉配置。
